To all whom it may concern: I

Be it known that I, JAMES L. Woonsrnn, a resident of Lincoln,in thecounty of Lancaster and Stateof Nebraska, have inventedcertain it restruction which whenapplied forms a' finish new and useful Improvementsin Chimney- Oaps, of which the following is a specification.

This invention relates to improvements in chimney-caps, and refers morespecifically to r a metal chimney-cap adapted to be applied to the topof an ordinary brick or analogous chimney. V

Among the salient objects of the invention are to provide a constructionwhich is capa ble of being readily adjusted to fit chimneys of differentdimensions; to provide a coning member for the chimney to which may bereadily applied extension members, if de-' sired, to carry the chimneyto a greater height;

to provide a construction which when placed in position serves toprotect the top of the masonry structure and at the same time serves tobind the upper course of bricks together,

so as to prevent disintegration of the chimney; to provide aconstruction comprising a base member and a cap member proper, the capmember being detachably connected with the base member; to provide meansfor. adjustably connecting the cap member with the base member, so thatthe latter is capable of lateral adjustment to bring it. into accurateregister with the chimney-opening; to provide a construction which may,if preferred,

j be secured to the masonrywithout the em ployment of cement or otherpermanently uniting material, and in general to provide a simple,economically-constructed, durable, and sightly construction ofthecharacter referred to.

To the above ends the invention consists in the matters hereinafterdescribed, and more particularly pointed out in the appended claims, andwill be more readily understood from the following description,reference being had to the accompanying drawings, forming a part of thedescription, in which-- Figure 1 is a top plan view of the base member.Fig.2 is an under side or bottom Fig. 3 is a side elevation of the basemember applied to the top of a chimney. Fig. 4 is a plan view of thedetachable cap member. Fig. 5 is a and applied to the top of a chimney.

Describing first the base member,- 1 designates as a whole the latter,and 2, 3,4, and 5, respectively, designate a set of similar angularplate members, each being of right-angle form or L shape in plan view,provided around its external margin with a downwardly-extending flange 6perpendicular to the main plane ofthe plate and provided also with aslot 7, arranged in alinement with the angle which bisects the rightangle included between the outer margins of the plate and ofconsiderable length, as indicated clearly in Figs. 1 and 2. The set ofangle members is adapted to fit together in partially-overlappedrelation, so that the size of the rectangular opening 8 outlined bytheir inner margins may be increased or diminished by adjusting theplates to overlap more or less, as required. In order to secure theplates together and in adjusted relation to each other, the overlappingparts are respectively provided with slots and apertures,

as indicated at 9 and 10, respectively, to re.

c'eive clamping-bolts 11, the slots 9 being arranged to extend parallelwith the adjacent marginal edges of the overlapping parts, as shownclearly in Figs. 1 and 2. Preferably in order to simplify the matter ofassembling and adjusting said plate members each is provided in one ofits L-shaped arms with a bolt-aperture and in its other arm with one ormore slots, (two in the present instance,)

so that each member will in part underlie one of the other members andin part overlie another, also as indicated clearly in said Figs. 1 and2. These slots arranged in longitudinal alinement of each other arepreferably provided instead of a single slot equal to the length of thetwo inorder to avoid as much as possible weakening the structure. Saidplate members may be" formed readily of sheet-metal structure into thedesired form by means of dies, or. they may becast, the latterconstruction being usually preferable.

Describing now the cap member, (designated as a Whole 12,) this consistsof a main body 13, having upwardly-converging sides which merge into andterminate at the upper edge in a circular or oval rim 14, an annularter.

shoulder 15 being provided at the conjuncture of the converging sideswith the rim 14, which serves to support a pipe-extension piece in caseit be found desirable to employ the lat- The main body 13 is provided atits lower edge with a base-flange 16, which is adapted to rest flat uponthe base memberl, hereinbefore described, and is provided at each of itsfour angles with an L-shaped slot 17, the several slots 17 being adaptedto register with the obliquely-disposed slots 7 of the base member.Owing .to the L-shaped form of the corner-slots 17 and the obliquedisposition of the slots 7, this arrangement provides practically foruniversal lateral adjust ment of the cap member upon the base memberand, furthermore, permits the base member to be expanded or contractedas a whole, to a considerable extent without carrying the oblique slotsof the base out of the range of the corner-slots of the cap member. Thebase member and cap member may be readily clamped together in adjustedposition by means of ordinary clamping-bolts 18 inserted through theregistering parts of the slots, as shown clearly in Fig. 6.

The base member may be secured to the top of the chimney either bycontracting or telescoping together its parts until its dependingflanges 6 closely embrace and rest in clamping engagement with the sidesof the chimney and then fastening the adjustingbolts 11 to unite theparts rigidly, or the base member may be adjusted to the chimney-top andthen after the cap member has been applied its exposed outer marginscemented to the chimney. In the latter case the unoccupied and exposedportions of the oblique slots 7 will serve as anchor-openings throughwhich the cement or mortar maybe forced and united with the underlyingmasonry. In this connection it will be obvious that the base member maybe employed without the cap member, if it be so desired, and in suchcase will serve to protect the top ofthe chimney perfectly from theweather and bind the masonry together in such manner as to preventcracking or disintegration. After the base member has been applied tothe chimney the cap member is adjusted to the base member, and in soadjusting it it may be shifted laterallyin one direction or the otheruntil its opening registers or is in vertical alinement with the throatof the chimney. 'It is then secured in position by means of theclamping-bolts 18, it being understood that these latter bolts will beinserted through the slots 7 of the base memher before the latter isapplied to the chimney, so that the threaded ends of the bolts stand upstud fashion to receive the cap member. It may also be noted that thecon struction of the cap member is such that it may be usedindependently of the base member, being in such case cemented directlyto the top masonry of the chimney. In such case the slots 17 serve asanchor-slots, and thus insure a more reliable fastening of the cap tothe masonry. The cap member may also be constructed either of sheetmetal or of cast metal, the latter being preferred both for economy ofmanufacture and durability and also as alfording a more rigid structure,which is important in case it be necessary to use an extension-pipe toincrease the height of the chimney.

From the foregoing description it will be seen that I attain the severalobjects of my invention hereinbefore enumerated and produce a devicecapable of being readily applied to chimneys widely varying in size andshape, that the construction as a whole forms a very efficient andneat-appearing device, and that either member may be used independentlyof the other, thus enabling the dealer to supply all reasonable demands.

It will be understood that the details of construction may be modifiedto some extent without departing from the invention, and I do not,therefore, limit myself to the precise details shown, except to theextent that the same are made the subject of specific claims.

I claim 1 1. A chimney protecting cap comprising a plurality of platemembers having overlapping parts and downturned-flange margins, each ofsaid plate members being provided with a radially-extending slot, someof said members having slots extending parallel with their marginaledges, others of said members having apertures to register with saidlatter slots whereby the overlapping parts of said plate members areadjustably secured together to form said cap.
